Check out the “Getting Started with the Hedera Token Service” video tutorial in JavaScript here. Token Keys
- If any of the token key types (KYC key, Wipe key, Metadata key, etc) are not set during the creation of the token, you will not be able to update the token and add them in the future
- If any of the token key types (KYC key, Wipe key, Metadata key, etc) are set during the creation of the token, you will not be able to remove them in the future
NFTs
For non-fungible tokens, the token ID represents an NFT class. Once the token is created, you must mint each NFT using the token mint operation.
Note: The initial supply for an NFT is required to be set to 0.
Token Properties
Transaction Signing Requirements
- Treasury key is required to sign
- Admin key, if specified
- Transaction fee payer key
Transaction Fees
- For fungible tokens, a
CryptoTransfer fee is added to transfer the newly created token to the treasury account
- Please see the transaction and query fees table for the base transaction fee
- Please use the Hedera fee estimator to estimate your transaction fee cost

Get Transaction Values
| Method | Type | Description |
|---|
getTokenName() | String | Returns the name of the token |
getTokenSymbol() | String | Returns the symbol of the token |
getDecimals() | int | Returns the number of decimals |
getInitialSupply() | long | Returns the initial supply of tokens |
getTreasuryAccountId() | AccountId | Returns the treasury account ID |
getAdminKey() | Key | Returns the admin key |
getKycKey() | Key | Returns the KYC key |
getFreezeKey() | Key | Returns the freeze key |
getWipeKey() | Key | Returns the wipe key |
getSupplyKey() | Key | Returns the supply key |
getPauseKey() | Key | Returns the pause key |
getFeeScheduleKey() | Key | Returns the fee schedule key |
getMetadataKey() | Key | Returns the metadata key |
getFreezeDefault() | boolean | Returns the freeze default value |
getTokenType() | TokenType | Returns the token type |
getSupplyType() | TokenSupplyType | Returns the supply type |
getMaxSupply() | long | Returns the max supply |
getHighVolume() | boolean | Returns whether this transaction uses high-volume throttles |
This transaction supports high-volume entity creation
(HIP-1313). Setting setHighVolume(true) routes the transaction through dedicated
high-volume throttle capacity with variable-rate pricing. Always pair this with
setMaxTransactionFee() to cap your costs. //Create the transaction
TokenCreateTransaction transaction = new TokenCreateTransaction()
.setTokenName("Your Token Name")
.setTokenSymbol("F")
.setTreasuryAccountId(treasuryAccountId)
.setInitialSupply(5000)
.setAdminKey(adminKey.getPublicKey())
.setMetadataKey(metadataKey)
.setMetadata(metadata)
.setMaxTransactionFee(new Hbar(30)); //Change the default max transaction fee
//Build the unsigned transaction, sign with admin private key of the token, sign with the token treasury private key, submit the transaction to a Hedera network
TransactionResponse txResponse = transaction.freezeWith(client).sign(adminKey).sign(treasuryKey).execute(client);
//Request the receipt of the transaction
TransactionReceipt receipt = txResponse.getReceipt(client);
//Get the token ID from the receipt
TokenId tokenId = receipt.tokenId;
System.out.println("The new token ID is " + tokenId);
//v2.0.1
